I have a 20lb co2 tank with siphon tube for $75 plus actual shipping cost via UPS
You can save the shipping cost if you can pick it up at Sacramento CA.
This is great for your paintball weekends. No more paying some other chump $5 to fill your 9oz. tank. You can fill this 20lb tank up once and use it to fill yours and all your buddies tanks. It has been hydro tested in 2001, so you can assure to have it for along time.
